Laws of Motion question

2009 · Q155

NEETPhysicsLaws of MotionMCQ+4 / −1
The mass of a lift is 2000 kg. When the tension in the supporting cable is 28000 N, then its acceleration is :
  1. A
    4 m s−-−2 upwards
  2. B
    4 m s−-−2 downwards
  3. C
    14 m s−-−2 upwards
  4. D
    30 m s−-−2 downwards

Correct answer: A

AIPMT 2009 Physics - Laws of Motion Question 39 English Explanation
F – Mg = Ma

8000 = 2000a

$ \therefore $ Acceleration is 4 ms–2 upwards.
